You guys have sparked my interest into getting a comet to help with my form, but how well do the vibram ibex and innova super stingray at helping form compared to the comet? (since I already have those two mids)

Very limited experience with either but by all accounts you're probably good with them, especially as they beat in. For form work, the key is using a disc that is neutral in stability (just plain stable). Thrown clean with hyzer it should stay hyzer, clean with anhyzer it should stay anhyzer, clean and flat it should stay straight. The Comet (especially the X Comet) is extremely good at being neutral but there are lots of discs that work well enough. Most putters, practically all lids, and slower drivers in base plastic (Leo, Cheetah, Cyclone, JLS, etc) are all really good for form work as well. But again, the key word is neutral (stable). as close to HSS: 0, LSS: 0 as you can get.
